The importance of electric arc furnace steelmaking is evident from the escalated world production seen in steel industry. This book presents systematic and complete details on the current state of knowledge about metallurgical processes carried out in the electric arc furnace. It includes principles of construction of electric arc furnaces, applied construction solutions, and their operations (together with auxiliary/supportive devices). Modern technologies of melting of various grades steel are detailed, considering the participation of secondary metallurgy including theoretical backgrounds of chemical processes and reactions. It contains theoretical analysis and results of laboratory, model, and industrial tests. Features: Covers the practical aspects of electric arc furnace steelmaking including technological process. Discusses the operation issues of an electric arc furnace in a technical and technological context. Presents a systematic and complete knowledge about relevant construction solutions and metallurgical processes. Includes practical industrial benchmark indicators in the scope of equipment and technology. Analyses practical case studies from industry. This book aims at researchers, professionals and graduate students in Metallurgical Engineering, Materials Science, Electric Power Supply, Environmental Engineering, and Mechanical Engineering.

This book equips a reader with knowledge necessary for critical analysis of innovations in electric arc furnaces and helps to select the most effective ones and for their successful implementation. The book also covers general issues related to history of development, current state and prospects of steelmaking in Electric Arc Furnaces. Therefore, it can be useful for everybody who studies metallurgy, including students of colleges and universities. The modern concepts of mechanisms of Arc Furnace processes are discussed in the book at the level sufficient to solve practical problems: To help readers lacking knowledge required in the field of heat transfer as well as hydro-gas dynamics, it contains several chapters which provide the required minimum of information in these fields of science. In order to better assess different innovations, the book describes experience of the application of similar innovations in open-hearth furnaces and oxygen converters. Some promising ideas on key issues regarding intensification of the heat, which are of interest for developers of new processes and equipment for Electric Arc Furnaces, are also the concern of the book It should be noted, that carrying out the simplified calculations as distinct from using "off the shelf" programs greatly promotes comprehensive understanding of physical basics of processes and effects produced by various factors. This book gives numerous examples of such calculations performed by means of simplified methods and formulas. Getting familiar with material in this book will allow the reader to perform required calculations on his / her own without any difficulties.

Separation processes—or processes that use physical, chemical, or electrical forces to isolate or concentrate selected constituents of a mixture—are essential to the chemical, petroleum refining, and materials processing industries. In this volume, an expert panel reviews the separation process needs of seven industries and identifies technologies that hold promise for meeting these needs, as well as key technologies that could enable separations. In addition, the book recommends criteria for the selection of separations research projects for the Department of Energy's Office of Industrial Technology.

This book describes improvements in the iron and steel making process in the past few decades. It also presents new and improved solutions to producing high quality products with low greenhouse emissions. In addition, it examines legislative regulations regarding greenhouse emissions all around the world and how to control these dangerous emissions in iron and steel making plants.

Steel Making is designed to give students a strong grounding in the theory and state-of-the-art practice of production of steels. The book is primarily focused to meet the needs of undergraduate metallurgical students and candidates for associate membership examinations of professional bodies (AMIIM, AMIE). Besides, for all engineering professionals working in steel plants who need to understand the basic principles of steel making, the text provides a sound introduction to the subject. Beginning with a brief introduction to the historical perspective and current status of steel making together with the reasons for obsolescence of Bessemer converter and open hearth processes, the book moves on to : • elaborate the physicochemical principles involved in steel making • explain the operational principles and practices of the modern processes of primary steel making (LD converter, Q-BOP process, and electric furnace process) • provide a summary of the developments in secondary refining of steels • discuss principles and practices of ingot casting and continuous casting of steels • emphasize an increasing need to protect our environment and utilize waste energy • explain transport processes, simulation, and modelling relevant to the developments in steel technology. The book provides considerable information in an easily assimilable form and makes an ideal introduction to the complex subject of steel technology.

This is a translation of the latest German edition of this work, and reflects the growth in importance of electrical steelmaking during the last decades. The contributors to the book discuss the latest technology giving information about the prerequisites and conditions necessary for the successful operation of a modern electric furnace steelworks. As well as coverage of almost every technical aspect of electrical furnace steel production, there are chapters on the history of the process, on its effect on the environment, and on ways of costing and calculating economic efficiency.
